Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging machine disassembly, in particular to a cigarette protection plate positioning tool. Background Art

[0002] Cigarette packaging machine is a kind of equipment used to pack cigarettes into groups. Taking the ZB25 and ZB45 packaging units produced by Shanghai Tobacco Machinery Co., Ltd. as an example, the main function of the No. 1 wheel is to receive the cigarette groups from the mold box conveyor belt, and then rotate intermittently counterclockwise to transfer the cigarette groups to the No. 2 wheel. Figures 1 to 3 As shown, the first wheel mainly includes: a wheel body 01, a tobacco end cigarette shield 02 and a filter end cigarette shield 03. The tobacco end cigarette shield 02 is arranged at the radial end of the middle wheel seat 012 of the wheel body 01 through a bolt pair, and the filter end cigarette shield 03 is arranged at the radial end of the upper wheel seat 013 of the wheel body 01 through a bolt pair. The extension direction of the filter end cigarette shield 03 and the tobacco end cigarette shield 02 is consistent. The space between the two is used for placing cigarettes, so that the filter end cigarette shield 03 and the tobacco end cigarette shield 02 play a role in protecting cigarettes.

[0003] At present, before repairing the damaged smoke guard plate, the filter end smoke guard plate 03 and the tobacco end smoke guard plate 02 need to be disassembled first, and then the repaired smoke guard plate is installed on the wheel body 01. The distance between the outer end of the smoke guard plate and the axis of the wheel body 01 is relatively long, so it is difficult to use existing common tools to ensure the parallelism of the filter end smoke guard plate 03 and the tobacco end smoke guard plate 02, which causes the No. 1 wheel to interfere with the cigarette group push plate when rotating, and finally causes damage to parts or friction with the body.

[0004] Therefore, how to quickly install the filter end cigarette protection plate 03 and the tobacco end cigarette protection plate 02 in parallel on the wheel body 01 is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a cigarette guard plate positioning tool, which can ensure that both the filter end cigarette guard plate and the tobacco end cigarette guard plate are along the radial direction of the wheel body and are installed on the upper wheel seat and the middle wheel seat respectively, thereby solving the problem of difficulty in installing the above two types of cigarette guards in place.

[0006] To achieve the above-mentioned purpose, the present invention provides a cigarette guard plate positioning tool, comprising: a base for supporting a wheel body; a first positioning portion connected to the base for determining the radial installation positions of the filter end cigarette guard plate and the tobacco end cigarette guard plate relative to the wheel body, the first positioning portion having a first positioning surface for abutting against the end face of the filter end cigarette guard plate and placing the filter end cigarette guard plate along the radial direction of the wheel body; a second positioning portion provided on the base for determining the axial installation position of the tobacco end cigarette guard plate relative to the wheel body, the second positioning portion having a second positioning surface for supporting the tobacco end cigarette guard plate and placing the tobacco end cigarette guard plate along the radial direction of the wheel body.

[0007] Preferably, two first positioning portions are provided, and the two first positioning portions are provided at two ends of the base.

[0008] Preferably, the first positioning portion is specifically a positioning plate, and the positioning plate extends upward perpendicular to the base.

[0009] Preferably, two second positioning portions are provided, and the two second positioning portions are arranged between two positioning plates.

[0010] Preferably, the two second positioning parts are arranged at the bottom of the two positioning plates.

[0011] Preferably, the second positioning portion is specifically a support block for abutting against the bottom of the tobacco end tobacco protection plate.

[0012] Preferably, a positioning blind hole communicating with the mounting hole of the lower wheel seat is provided at the central position of the base, so that the wheel body can be fixed by inserting a positioning pin into the mounting hole and the positioning blind hole in sequence.

[0013] Preferably, a clamping block for connecting to the bottom end of the camshaft is further provided at the central position of the base, and the clamping block has a clamping groove for clamping the straight-line protrusion at the bottom end of the camshaft.

[0014] Preferably, the card slot is in a straight line shape.

[0015] Compared with the above-mentioned background technology, the cigarette guard plate positioning tool provided by the present invention ensures the parallelism between the cigarette guard plate at the filter end and the cigarette guard plate at the tobacco end through the first positioning part and the second positioning part. Specifically, the wheel body is placed at the preset position of the base. On the one hand, the cigarette guard plate at the tobacco end is mounted on the second positioning surface so that the cigarette guard plate at the tobacco end extends radially along the wheel body, and the cigarette guard plate at the tobacco end is moved radially along the wheel body to a position against the first positioning part, and finally the cigarette guard plate at the tobacco end is fixed to the middle wheel seat by a bolt pair; on the other hand, the cigarette guard plate at the filter end is moved radially along the wheel body so that the end face of the cigarette guard plate at the filter end is against the first positioning surface to ensure that the cigarette guard plate at the filter end extends radially along the wheel body, and then the cigarette guard plate at the filter end is fixed to the upper wheel seat by a bolt pair.

[0016] It can be seen that after installation, the filter end cigarette guard plate and the tobacco end cigarette guard plate both extend along the radial direction of the wheel body, that is, the extension directions of the filter end cigarette guard plate and the tobacco end cigarette guard plate are parallel, thereby avoiding interference between the No. 1 wheel and the cigarette group push plate.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Please refer to Figures 4 to 6 , Figure 4 A front view of a smoke protection plate positioning tool provided by the present invention; Figure 5 for Figure 4 A top view of Figure 6 This is a schematic diagram of the working principle of a smoke protection plate positioning tool provided by the present invention.

[0029] The present invention provides a smoke protection plate positioning tool, such as Figures 4 to 6 As shown, the cigarette guard plate positioning tool comprises: a base 1, a first positioning portion 2 and a second positioning portion 3. The base 1 is used to support the wheel body 01, so as to place the lower wheel seat 011 at a preset position of the base 1. Preferably, the base 1 is plate-shaped; the first positioning portion 2 is connected to the base 1, and determines the radial installation positions of the filter end cigarette guard plate 03 and the tobacco end cigarette guard plate 02 relative to the wheel body 01 by abutting against the filter end cigarette guard plate 03 and the tobacco end cigarette guard plate 02; the second positioning portion 3 is provided on the base 1, and is used to determine the axial installation position of the tobacco end cigarette guard plate 02 relative to the wheel body 01.

[0030] Among them, Figure 4 and Figure 6 As shown, the above-mentioned first positioning portion 2 has a first positioning surface 21, and the first positioning surface 21 can be abutted against the end surface of the filter end cigarette protector 03, and the filter end cigarette protector 03 is placed along the radial direction of the wheel body 01. Of course, if the first positioning surface 21 extends along the axial direction of the wheel body 01 to the position of the middle wheel seat 012, the first positioning surface 21 can also be abutted against the end surface of the tobacco end cigarette protector 02, so as to determine the radial installation position of the tobacco end cigarette protector 02 relative to the wheel body 01; the above-mentioned second positioning portion 3 has a second positioning surface 31, and the second positioning surface 31 can support the tobacco end cigarette protector 02, and the tobacco end cigarette protector 02 is placed along the radial direction of the wheel body 01.

[0031] It should be noted that, when the wheel body 01 is placed at the preset position of the base 1, from the radial direction of the wheel body 01, the horizontal (i.e. the radial direction of the wheel body 01) distance from the above-mentioned first positioning surface 21 to the preset position of the base 1 should be the radial distance from the end faces of the above-mentioned two types of smoke guards to the axis of the wheel body 01, thereby ensuring that the filter end smoke guard 03 and the tobacco end smoke guard 02 can be installed in place relative to the upper wheel seat 013 and the middle wheel seat 012 respectively; the position of the above-mentioned second positioning surface 31 should ensure that when the tobacco end smoke guard 02 is mounted on the second positioning surface 31, the installation end of the tobacco end smoke guard 02 is located at the middle wheel seat 012 in the axial direction of the wheel body 01.

[0032] Here, the working principle of the above-mentioned cigarette protection plate positioning tool is explained with respect to its structural structure: the first step is to place the wheel body 01 on the base 1, and ensure that the lower wheel seat 011 is located at the preset position of the base 1; the second step is to respectively install the filter end cigarette protection plate 03 and the tobacco end cigarette protection plate 02. Specifically, on the one hand, the filter end cigarette protection plate 03 is roughly moved along the axial direction of the wheel body 01 so that its installation end is located at the upper wheel seat 013, and the filter end cigarette protection plate 03 is moved along the radial direction of the wheel body 01 so that the end face of the filter end cigarette protection plate 03 is against the first positioning surface 21. Since the end face of the filter end cigarette protection plate 03 is wider, it can ensure that the above-mentioned end face is completely fitted with the first positioning surface 21, thereby making the filter The end tobacco shield 03 is placed along the radial direction of the wheel body 01, and then the mounting end of the filter end tobacco shield 03 is fixed to the upper wheel seat 013 by a bolt pair; on the other hand, since the end face of the tobacco end tobacco shield 02 is narrow, and it is difficult to ensure that the above-mentioned end face can completely abut against the first positioning surface 21, the tobacco end tobacco shield 02 is roughly moved along the axial direction of the wheel body 01 so that it is carried on the second positioning surface 31, and then the tobacco end tobacco shield 02 is placed along the radial direction of the wheel body 01, and the tobacco end tobacco shield 02 is moved along the radial direction of the wheel body 01 so that the end face of the tobacco end tobacco shield 02 abuts against the first positioning surface 21, and finally the mounting end of the tobacco end tobacco shield 02 is fixed to the middle wheel seat 012 by a bolt pair.

[0033] It should be noted that the mounting ends and end faces of the filter end smoke guard plate 03 and the tobacco end smoke guard plate 02 respectively correspond to the two ends of the above-mentioned two types of smoke guard plates, wherein the so-called "mounting end" specifically refers to the end of the filter end smoke guard plate 03 and the tobacco end smoke guard plate 02 close to the axis of the wheel body 01 when they are installed on the wheel body 01.

[0034] It can be seen that the core of the present cigarette guard plate positioning tooling is twofold. One is to install the filter end cigarette guard plate 03 on the upper wheel seat 013 along the radial direction of the wheel body 01 through the first positioning surface 21; the other is to install the tobacco end cigarette guard plate 02 on the middle wheel seat 012 along the radial direction of the wheel body 01 through the second positioning surface 31, so as to ensure the parallelism of the filter end cigarette guard plate 03 and the tobacco end cigarette guard plate 02, thereby solving the problem of interference between the No. 1 wheel and the cigarette group push plate during rotation, thereby avoiding friction between the parts of the cigarette packaging machine and the machine body.

[0035] like Figure 1 and Figure 2 As shown, since the wheel body 01 is provided with four filter end cigarette protection plates 03, and the four filter end cigarette protection plates 03 are arranged in pairs on both sides of the radial direction of the upper wheel seat 013, it is preferred that Figures 4 to 6 As shown, two first positioning parts 2 are provided, and the two first positioning parts 2 are respectively arranged at the two ends of the base 1, and the wheel body 01 is placed between the two first positioning parts 2, so that the installation of four filter end cigarette protection plates 03 can be completed at one time without rotating the wheel body 01.

[0036] Considering that the end faces of both the filter end cigarette shield 03 and the tobacco end cigarette shield 02 are flat surfaces, the above-mentioned first positioning portion 2 is preferably a positioning plate, and the positioning plate is arranged perpendicular to the upper surface of the base 1. Accordingly, the first positioning surface 21 is the side surface of the positioning plate.

[0037] Likewise, if Figure 1 and Figure 2 As shown, since the wheel body 01 is provided with four tobacco end protection plates 02, and the four tobacco end protection plates 02 are arranged in pairs on both sides of the radial direction of the middle wheel seat 012, it is preferred that Figures 4 to 6 As shown, two second positioning parts 3 are provided, and the two second positioning parts 3 are provided between the two positioning plates, so that the installation of four tobacco end protection plates 02 can be completed at one time without rotating the wheel body 01. As a further preferred embodiment, the two second positioning parts 3 are provided at the bottom of the two positioning plates, that is, the positioning plates and the second positioning parts 3 are designed to be integrally formed.

[0038] Considering that the lower surface of the tobacco end tobacco guard plate 02 is a flat surface, the above-mentioned second positioning portion 3 is preferably a support block, the upper surface of the support block is parallel to the upper surface of the base 1, and is used to support the tobacco end tobacco guard plate 02, thereby placing the tobacco end tobacco guard plate 02 along the radial direction of the wheel body 01. In other words, the upper surface of the support block is the second positioning surface 31.

[0039] In order to prevent the wheel body 01 from rotating or translating relative to the base 1 at the preset position and deviating from the preset position, it is preferred that Figure 5 and Figure 6 As shown, a positioning blind hole 11 that can communicate with the mounting hole 0111 of the lower wheel seat 011 is provided at the central position of the base 1 (i.e., the preset position for placing the lower wheel seat 011), and then the wheel body 01 is fixed by inserting the positioning pin 4 into the mounting hole 0111 and the positioning blind hole 11 in sequence. Of course, the positioning pin 4 can also be directly provided on the upper surface of the base 1, and then the wheel body 01 is fixed to the base 1 through the cooperation between the mounting hole 0111 and the positioning pin 4.

[0040] Based on all the above technical contents and according to actual measurements, the average time consumed to install the tobacco end cigarette protector 02 and the filter end cigarette protector 03 using the cigarette protector positioning tool is 12 minutes. Compared with the time consumed for installation operations using ordinary tools in the prior art, the cigarette protector positioning tool can save the operator 10 minutes of work.

[0041] In addition, in the prior art, Figure 2 and Figure 3As shown, the number one wheel also includes a cam 015 and a camshaft 014. The camshaft 014 is arranged through the wheel body 01 and can rotate relative to the wheel body 01. The bottom end of the camshaft 014 is provided with a straight protrusion 0141, and the straight protrusion 0141 is located in the U-shaped groove 0112 of the lower wheel seat 011. The top end of the camshaft 014 is fixed with the cam 015 through the nut 016, so that the cam 015 is located in the groove of the upper wheel seat 013. When the cam 015 is damaged and needs to be repaired, the nut 016 needs to be removed first to remove the damaged cam 015. Since the camshaft 014 can rotate with the nut 016, the camshaft 014 also needs to be fixed, and then the nut 016 can be screwed out from the top end of the camshaft 014.

[0042] To this end, a clamping block for connecting the bottom end of the camshaft 014 is also provided at the central position of the base 1, and the clamping block has a clamping groove for clamping the straight protrusion 0141. Specifically, the lower wheel seat 011 is placed at the central position of the base 1, so that the clamping block is located in the U-shaped groove 0112, and the straight protrusion 0141 is matched with the clamping groove, so that the camshaft 014 cannot rotate with the nut 016, so that the operator can unscrew the nut 016 from the top end of the camshaft 014 and remove the cam 015.

[0043] Preferably, the slot is designed to be in a straight line shape. Of course, the slot can also be designed to be in a cross shape, a cross shape, or other shapes, as long as the straight line protrusion 0141 can be inserted into and clamped.

[0044] It should be noted that in the description of the present invention, the directions or positional relationships indicated by “upper”, “lower”, “top”, “bottom” and “horizontal” are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than limiting the elements or parts referred to to have a specific direction, and therefore cannot be understood as limiting the present invention. In addition, in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0045] The above is a detailed introduction to the smoke guard plate positioning tooling provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
